Greece attracted just a single bid for its biggest and most historic shipbuilding facility, sparking speculation that the country will pull the plug on the sale.

The only offer for Hellenic Shipyards — better known as Skaramangas — came from Pyletech Shipyards, an entity led by low-profile Greek shipping investor Theodore Priovolos, which offered €15.1m ($18.4m) for the yard.

Some observers were underwhelmed.
